Perhaps, but I suppose I'd personally nudge a friend to post it for me? Maybe humility isn't valued much in the Valley, but coming from elsewhere it feels off.
This is a side of me I would like more people to see. The whole person. So I submitted the article. I grew up in the South and don't live in the Valley. It required a bit of humility to even share this side of me, it's very personal, and in someways, not very flattering, but I wish I knew that successful people also come from very average backgrounds.
Personally I find the idea of asking a friend to post a self-promotional link without disclosing the affiliation, because I'm too "humble" to post it... quite the opposite of humble.
